1./ 'o all 'whom 'it may concern lle it known that l, lL-rNroN lilc/(tmnnmi, :t citizen oi' the Un ed States, residing at lios ngeles, in 'the county of Los tmgeles und State of Calii'orniau Ahave invented n new nucl useful {lil-Burnett it which the 'tollen-ing is zL-speciticution.

The main object of the present invention is to provide u. burner which will be adopted to spray and burn comparatively heavy oils with light pressure in distinction to the comparatively heavy pressure which is gen erully employe with such oils in connection with furnaces, etc.` By .using light pressure of say, two pounds or less per square inch, l um enabled to einploj,y the burner in plants such domestic iurnnces in which high `pressure is not available. l Otherobjects oli the invention Will sppeur hereinafter.

"llie accompanying drawings illustrate an embodiment of the invention, und referring thereto:

Figure l. is @longitudinal section of the burner. Fig. Q is s longitudinal section the burner head on en cnlargefl scalo. Fig. 3 is transverse section on line :r3-x3 in Fig. 2. lig.. is e section' on line azi-wc* in Fig. 3. Fig. 5 is e qi W 'similar to showing a modifie-fl form the inven-` tion.

'ilhe burner comprises an outer tube l ving nir anni an inner tube 2 for con- ,D oil, and s lmrner head or atoniizing neiuoer consisting of e. cylindrical member connected to the inner tube 2 enti p'ofor 7 idecl ,with s burner outlet e, communicating with the seid tube 2 und l.

The outer tube' 1 muy be connected' to :my suitable source of nir or steam supply, for exuniple, to u 6, one brunch G of which is adopted to receive an nir vor steam supply pipe, und the other 'oruufch of which is plugged as et 8 to receive and support 'the inner 'tube 2. The burner heeel 3 may he screwed onto the forward end of. the inner "tube 2 and screvefl into e boss i0, extending forwardly from a screw cap l1, which. screws on the forward enfl oi" the outer tube 1. The central passage or bore 8 of the burner head is suhstnutiullj.' continuous with the bore of tube 2 enel the outlet Il. comn1unicetes with the foi-Werd end of seid pafsege 8', seid outletaring forwsrclly to its discharge opening. plurality of perforutious or passages 9 extend through the woll of the member I3, connnunicnting at their outer ends with rthe interior of the outer tube l, und extending obliquely forward und inward und opening' at their inner ends into the inner pussnge or bore S of the inexnher These passages 9 are also `Lrclierabl7 set in un' angle with respect to radial rlirection so that they extenfl tangentially 'to the bore or passage 8 in member 8, es shown in Fig. The said passages 9 may he tiered toward their outlet ends as sliou'n in Figs. 2, 3 and l, so as to provide for expansion of the issuing elastic fluid, or ns shown iu Fig. 5, they may he of uniform diameter throughout.

The opertion is as follows: @il is snppliecl to the tube Ff) by any suitable means and passes forwardly in -seifl tube and into the passage S Within the member Air, steam or other elastic medium is supplied through the inlet 6 and passes forwardly in the outer tube l and `through 'the ohlique passage 9 into the current of oil es it passes along the ocre 8. The spraying fluid {Suss- `ing obliquely into the body of oil in the general direction of motion of the oil and tengentiully to the Wall et the boro 8"', forces its Wayv throughv the oil anrl et the suine time imparts to the oil e rotary movement, these tufo actions serving to break up the oil and force it forwardly in e film or' layer along the flaring orconical. Well of the outlet 4l, the passages 9 being preferably set substantially in slinement unich-the seid Wall. ln this' operutionthe enireiningeftect of the elast-ic medium ouille eil, to* getlier with lt ieresistance oeredl to the :torsev ward movement of the oil by the friotiini on the well o the ontlet, ca -uses the oil to be spread in s' thin film and to loe broken up or utornized und thoroughly mixed with the nir or elastic medium, the oil passing in n conical divergent sheet of sterilized liquid und vapor from the Cliselmrge end of the outlet 4.
